Print not sticking to bed... bluetape

This is Paper Tape, and is similar to blue tape they in fact both have a medium adhesion tack.
I even printed on a sheet of inkjet printer paper taped to the bed.

I have the best luck printing on the Vinyl Application Paper Tape. Maybe if I experimented with bed temperatures I could get my Build surface to stick better, but why this works for me.
And maybe the Build surfaces I purchased were counterfeit. I have no way on knowing. They just did not work well.
I even purchased a different build surface they are still unused in the packages.

if you look at the last picture you see that the filament is not squeezed on to the bed.
if you didn't change the z offset in the slicer software
or change any hardware
you need to check if the nozzle hight is still good.
Check multiple times, after a new zero. (paper calibration)
Don't change any thing between the multiple zeroings, It is possible that the zero sensor doesn't repeat accurate engough

For anyone having problems with bed adhesion, I recommend RigidInk PLA+. In fact I find it unusable on two of my printers, one with a PEI-covered bed and one with an uncoated float glass bed, because it sticks so well that I can't get the prints off without damaging the bed. But my third printer is a SCARA with no bed, it prints on the desk area in front, which I cover with blue tape. Most of the blue tape strips are quite dirty now and the adhesion is just right. Annoyingly, one isn't, and every time I print that strip sticks too well to the print; so part of it comes off with the print and I have to replace it again... with another clean piece.

I don't print with PLA but i believe the usuall fix for some of these issues is to turn on the cooling fan after a couple of layers.
Although everyones machine will need different settings i suspect your temperatures are too high. I believe many will use 180-195 for the main layers.
